WINDOW ovum.

Application filed June 1 This invention relates to new and useful im rovernents in window guards. I

The primary object of the inventionis the provision of a guard for a window which includes amultip icity of bars carried by supporting, flexible members, which with the of the following escr'iption.

In the accompanying drawings forminga part of the specification, and in. which like numerals are em paloyed to designate like parts throughout t e same, i

Figure 1 is a front elevational view of the f device embodying this invention when viewed from the inner s de of the window,

certain face boards of the window frame be-- ing removed for more clearly illustrating the window guard operating mechanism,

Figure2 is a vertical, sectional view taken on line II-II of Figure 1,

Figure 3 is a vertical sectional view similar to Figure 2 but shows the window guard wound upon. a carrier located within the win dow frame, V V I Figure 4 is a vertical sectional view taken upon'line IVIV of Figure 1,

Figure 5 is a horizontal sectional View taken upon line V,V of Figure 1,

Figure 6 is a horizontal sectional view taken upon line VI-VI of Figure 1,

Figure 7 is afragmentary enlarged horizontal sectional view of one side of the window frame, and shows the construction of the upper and lower window sashes and the shape of the window guard guiding strips carried by the vertical sides of the window frame, and

Figure 8 is a detail perspective view of a fragmentary portion of one of the flexible supporting members to which the bars are fastened at their ends.

In the drawings, wherein for the purpose of illustration is shown the preferred embodiment of this invention, the numeral 5 designates the bottom horizontal board of a s, 1925. Serial no. 37 954.

window frame which has extending verticaL ly therefrom the inner side boards 6 and 7 which have connected to their longitudinal edges the inner and outer facing boards 8 and 9 respectively. These inner and outer facing boards have their free longitudinal edges connected to the finishing boards 10 and 11 which extend in parallelism with. the

boards 6 and 7 respectively.

The'boards 6 and 7 arefprovided on their inner vertical faces, with window sash guiding strips 12 lower sash frames 13 slide.

cords 14 and sash weights 15 which function between which the upper. and.

These sash frames are provided with the usual sash.

in a well known manner for counter-balahc: i

ing the window sashes. The sash frame-s 131 are best illustrated in Figure 7 as being formed with rabbeted nner edges 16 which are intendedto .recelve the wlndow pane carrying frames 17 which have rabbeted edges 18 in which the window panes 19 are. held by thecement or other similar sub stance 20. These window panecarrying frames are hinged at 2.1 to the sash frames 13 and may be moved or swung horizontally inwardly, as illustrated in dotted lines in Figures 6 and 7, for permitting the panes to be easily cleaned;

Thevertical inner boards 6 and, 7 of the window frame have connected thereto the horizontal board 22 which is arranged in spaced relation to the top finishing board 23 and with the inner and outer facing boards 2st and 25 form a compartment 26 in the window frame. The board 22 is provided with a longitudinally extending slot 27 which is formed with its longitudinal sides converging downwardly for forming a tapering guide-way.

Connected to the vertical side boards Sand 7 anddepending truly ve-rtica'll from the opposite ends of theslot 27 are t e channelshaped guiding strips 28 which engage the bottomboard 5 at their lower ends and register with a slot 29 formed in the board 5.

Depending from the board 5 is an elongated chamber 30- which communicates with the said slot 29.

Journaled in the upper end portion of the boards 6 and 7 is a horizontal rod 31 which has a bevel gear 32 fastened to one end and meshing with a bevel gear 33 carried by the upper end of the vertical shaft 34 which is journaled in the brackets 35 and 36 fastened to the outer face of the side board 6; The

lower end portion of this shaft 34 has fastened thereto a bevel gear 37 which meshes with a bevel gear 38 carried by a stub shaft 39 which is journaled in a bearing :10 and has the crank handle a1 fastened to the outer end thereof. This structure is clearly illustrated in several of the figures and it will be understood by an inspection of the same that rotation of the crank handle in opposite directions will cause the rod 31 to rotate in opposite directions.

Fastened at their upper ends to the rod 31 at points arranged in close proximity to the side boards (5 and 7 are flexible supporting members 42, which in this showing are in the form of link chains. Figure 8 shows one 01' these chains 4-2 with the bifurcated end 43 of a guard bar as fastened to one link thereof. It is to be understood that a multiplicity of these bars as are fastened at their opposite ends to the flexible supporting chains 42 and are arranged in suitable spaced relation to each other.

In Figures 1 and 2 the flexible supporting chains and the guard bars are shown arranged to protect the entire length of the window opening to the window frame with the ends of the bars and the flexible supports received within these channel-shaped guiding strips 28. In Figure 3 these flexible supports and the bars are shown as being wound upon the rod 31 within the compartmeat 26, the lowest bar 11, however, still being arranged with its ends received within the guiding strips 28 and prevented from being withdrawn from these strips by the laterally projecting stop pins 45. These pins are employed for preventing the last bar 4 1 and the ends of the flexible supporting chains 4C2 from being drawn into the compartment :26.

It will he noted that Figures 2 and 3 show several links of the supporting chains 12 depending from the bottom bar 44. It is to be understood that when the flexible supporting chains and the bars are entirely unwound from the rod 31, these depending end links, which will be given the separate reference numeral 16, are received within the chamber 30. The spring pressed pins 47 are employed for being passed through one of these end links 46 for preventing an unauthorized person trom raising the bars 44:.

It is now believed that the manner of construction and method of operation of this window guard will be clearly understood from the above detailed description. It is further to be understood that the form of this invention herewith shown and described is to be taken as the preferred example of the same, and that various changes in the shape, size, and arrangement 01 parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described the invention, I claim:

1. In a window guard of the character described, a window frame comprising a head compartment having a bottom wall, there being a longitudinally extending slot in said bottom wall, a chamber beneath the sill of the frame, a flexible rolling grating supported in the con'ipartment and trailed grating in the compartment,

2. In a window guard of the character de- I scribed, a flexible rolling grating comprising spaced side chains and tubular rods bifurcated at their ends to receive a link of the adjacent chain and means for anchoring the ends of the rods to the chains.

3. In a window guard of the character described, a flexible rolling grating comprising spaced side chains and tubular rods bifurcated at their ends to receive a link of the adjacent chain, means for anchoring the ends of the rods to the chains, each chain link comprising a flat rectangular frame and a hook engaged with a frame bar of the adjacent link with the flat rectangular portion of the link received in the bifurcated rod ends.

In testimony whereof I affix my signature.

ANDREW NAGY.
